ENAMELING TABLE OR MACHINE.

SPECIFICATION forming part of Letters Patent No. 645,393, dated March13, 1900.

Application filed July 5, 1898. Serial No.685,188. (N0 model.)

To all whom it mag concern.-

Be it known that we, EDWARD 0. H0151.- scnna and JOHN CLIFFORD, citizensof the United States, residing in Chicago, in the county of Cook andState of Illinois, have invented a new and useful Improvement inEnameling Tables or Machines, of which the following is a specification.

Our invention relates to improvements in enameling tables or machinesemployed in the manufacture of enameled-iron bath-tubs or otherenameled-iron vessels or ware for holding the heated tub, vessel, orother article while the enameling-powder is being dusted upon the heatedvessel or article. These enameling-tables as heretofore constructed havesimply been provided on their upper face with a suitable cradle or seatto receive the vessel or article and properly hold it while the table isbeing inclined in the different positions required and turned or rotatedon its axis, and considerable loss of time and'labor, difficulty, andinconvenience have heretofore been experienced in the practical use ofsuch enameling-tables. The enameling-powder is liable to be sprinkledmore or less upon the outer surface of the heated tub or vessel, so thatthe outer surface of the vessel will be spotted with enamel andrequiring a good deal of time and labor to chip and grind it off inorder to produce a neat finished article. The rapid radiation of heatfrom the outside of the heated vessel produces great inconvenience tothe workmen employed in dusting or sprinklingthe enamelpowder and inturning the table and vessel thereon and also requiring the vessel to beheated to a higher heat and a greater loss of time between heats.

The object of our invention is to provide an enameling-table of anefficient, simple, and durable construction upon which the heated tub orvessel to be enameled may be quickly and conveniently placed and fromwhich it can be readily removed and by which the objections ordifficulties heretofore experienced may be overcome or obviated.

To this end our invention consists in an enameling-table provided withan extensible or collapsible case or muffler adapted to surround andprotect the outside of the heated tub or vessel to be enameled, so thatthe out side of the. heated tub or vessel will be protected from alldanger of the enamelingpowder being accidentally dusted or sprinkledupon it, thus entirely obviating all necessity for chipping or grindingoff the enamel from the outside of the tub, so that the workmen will belargely protected from the heat of the vessel, so that the heat will bebetter and longer retained in the vessel, thus rendering it unnecessaryto heat the vessel to so high a degree to receive the enameling-powderand also saving time in reheating the vessel to receive the nextcoating. The case or mufiier surrounding the heated tub or vessel to beenameled may be made collapsible or extensible in any suitable manner;but we prefer to make it in telescopic sections.

Our invention also consists in the novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described, and specified in-the claims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a side elevation of an enameling table or machine embodyingour invention. Fig. 2 is a vertical section on the line 2 2 of Fig. 1.Fig. 3 is a detail section on line 3 3 of Fig. 1, and Fig. 4 is a planview.

In the drawings, A represents the truck or table Bis mounted. O is aswinging shaft or spindle pivoted to the truck or frame A in the housingA thereon by the horizontal pivot or shaft O. The swinging spindle O isprovided with a counterbalance-weight (J to counterbalance the table Band the tub or vessel X to be enameled thereon.

The table B is provided on its upper surface with a number of projectingarms I) to form a cradle or seat to receive the vessel and hold the samein position while the table B is being inclined in different positionsand turned or rotated on its axis.

movable frame upon which the enameling- I B is a hub secured to thetable B and sur- IOO or vessel X to be enameled and to protect theoutside of the vessel from radiation of heat. This case is made in twoor more folding, extensible, or collapsible parts or sections 61 at,said parts or sections preferably being telescopic or telescoping onewithin the other, as illustrated in the drawings. The lower part orsection (1 of the case is thus secured rigidly to the table 13, whilethe upper or movable section d is movably connected to the lower sectionby the toggle-links F F. The toggle-links F each have a bent arm Fconnecting with the operating-lever F by the pivoted links F so that thepairs of toggle links or arms F F on each side of the case aresimultaneously operated from said lever F The toggle links or levers F Fon opposite sides of the case A are rigidly secured to a common shaft f,so that the toggle links or arms on both sides of the 'case'are likewisesimultaneously operated. The operating'lever F is provided with asquared shaft f to receive a removable hand-lever for turning said leverF.

To prevent any danger of the two sections d d of the case sticking orcatching one on the other, we provide the movable section d withantifriction-rollers (1 This facilitates the sliding of the telescopicsection.

To lock or hold the table 13 at any desired inclination, its swingingspindle O is provided with a rack or notched segment G, the notches g ofwhich are engaged by a sliding bar g, which is reciprocated in its guideG by a lever 9 and connecting-link g We claim- 1. The combination in anenameling-table,

ble, of a telescopic case or muffler, substan-' tially as specified.

3. The combination with an enameling-table,-of a case or mufflercomposed of telescopic sections connected together by toggle links orlevers, and means for simultaneously operating the toggle links orlevers, substantially as specified.

4:. The combination with the enameling-table B, of a telescopic case ormufiler D com posed of a fixed section d and a movable sec tion (Z,toggle-links F F, arms F operatinglever F and connecting-links F,substantially as specified.

5. The combination with the enameling-t-able B, of a telescopic case ormnfiier D composed of a fixed section 01 and a movable section (1',toggle-links F F, arms F operatinglever F and connecting-links F thetogglelinks F on opposite sides of the case being secured to a commonshaft, substantially as specified.

6. The combination with a rotating swinging enameling-table, of atelescopic case or muffler, and mechanism for opening and closing theparts or sections of said case, substantially as specified.
